UNSPSC 31163003: Metallic couplings

UNSPSC 31163003 Metallic couplings is a Commodity code that covers compression fittings, quick-insertion couplings, and related metallic connection components for water and sewer infrastructure systems. Recent state and local opportunities show procurement focused on brass and stainless steel water service couplings, compression fittings, and hydraulic quick-insert valves for pressurized and non-pressurized pipeline networks. Counties, cities, and utility authorities dominate the buyer base, driven by aging water and sanitary sewer infrastructure replacement projects and routine maintenance of distribution systems. The scope spans both one-time project buys and recurring annual supply agreements, with work including removal and replacement of existing metallic or PVC service connections, installation of new couplings during mainline rehabilitation, and acquisition of valves and fittings for water service restoration.

Recent activity appears concentrated in Florida, California, and Georgia. Pinellas County, Florida issued an IFB (solicitation 260652ITBC) in October 2026 for sewer and water main improvements that includes replacement of approximately 6,800 linear feet of 6-inch water main and related service connections with fire hydrant and gate valve installation, due November 5, 2026.
